Pyruvate kinase (PK) is an important glycolytic enzyme catalyzing the last step of glycolysis, transferring a phosphate group from phosphoenolpyruvate to ADP to yield one molecule of ATP and one molecule of pyruvate. Pyruvate kinase (PK) is an important glycolytic enzyme ...
Superoxide dismutase (SOD) catalyzes the dismutation of superoxide radicals to hydrogen peroxide and molecular oxygen. SOD plays a critical role in the defense of cells against the toxic effects of oxygen radicals. SOD competes with nitric oxide (NO) for superoxide anion (which ...
SOD2 is part of the iron/manganese superoxide dismutase family. It encodes a mitochondrial protein that forms a homotetramer and binds one manganese ion per subunit. SOD2 binds to the superoxide byproducts of oxidative phosphorylation and converts them to hydrogen peroxide and ...
